# How To Measure Bike Stem? (Solved)

So, what size of a bicycle stem do you require?

• With a mid-range stem size that ranges from 60 to 80 millimeters in length, the great majority of bikes offer a good compromise between handling efficiency and comfortable physical alignment. Advanced mountain cyclists frequently choose a short stem of around 40 millimeters in length, which allows for improved off-road handling and downhill velocity.

## How do I know what size stem to get?

To find out how long your bike’s stem is, take a measurement between the two vertical points shown above. The stem rise refers to the angle in degrees that the stem makes with respect to the fork steerer tube, and it has an impact on bike positioning and reach.

## How do you measure a road bike stem?

A rider can consider a range of frame sizes and geometries when picking components for a custom road bike design, which is particularly useful when building a mountain bike.

## How do you measure the diameter of a handlebar stem?

If you don’t have callipers, you may simply use a measuring tape to get the measurements you need. Simply wrap the Oi around the bar at the place where you wish to attach it to obtain the circumference size, which you can then divide by pi (…. mmmm) to obtain the diameter size, for example 99.9mm / = 31.8mm. If you don’t have any tape, you can use a piece of paper instead (or string).

Generally speaking, you should strive for a stem length of between 50mm and 80mm on most current mountain bikes. Long stems are more stable while climbing with narrow handlebars, which makes them ideal for rock climbing. That’s all there is to it.
